This entry is found at the C-terminal of Nitric oxide-associated protein 1 (NOA1) from animals and rice, BPG2 from Arabidopsis and YqeH from B. subtilis. YqeH is an orthologue of NOA1. This domain has a beta-sandwich structure with homology to the RNA-binding regulator TRAP, and the hypoxia factor pVHL. The residues for RNA recognition in TRAP are conserved in members of this entry, suggesting that these are G-proteins that may regulate nucleic acid recognition [1].	Domain
